@slivingston Despite the claim that all checks completed, in fact the conda-based tests did not complete. SeeOS/BLAS test matrix run. It looks like the conda test matrix gets created but does not run.

The error is

Error when evaluating 'strategy' for job 'test-conda'. .github/workflows/os-blas-test-matrix.yml (Line: 277, Col: 15): Error parsing fromJson,.github/workflows/os-blas-test-matrix.yml (Line: 277, Col: 15): Error reading JToken from JsonReader. Path '', line 0, position 0.,.github/workflows/os-blas-test-matrix.yml (Line: 277, Col: 15): Unexpected value ''

Good catch. Yes, I am investigating this and a similar change for Slycot on which I am working.

It looks like the same hidden error happened 2 weeks ago in a different PR:https://github.com/python-control/python-control/actions/runs/13107250760

Commit1ceeeea deleted required imports ina test matrix generation script, resulting in an uncaught exception. The backtrace from Python would then be used as the saved output in astep of the workflow file. One of the next jobs tries to parse this output as JSON, hence the error from JsonReader. This is treated as a syntax error in the workflow file, thus an incomplete rather than a failed job.

I modified the workflow files so that errors from the test matrix generation scripts surface clearly as failed jobs.

...actually, still debugging. I will finish it in the morning.

This is ready for review.

Sorry for the extra delete in1ceeeea

Sorry for the extra delete

@bnavigator No worries! I only intended to find the origin, not accuse anyone.
